 * browser as an image. That image sees no stylesheets of its own, so
 * everything the card needs has to live here.
 *
 * This is the lab's card, ported (tools/lab/ui/card.css). A card saved from
 * the site and one saved from the lab are meant to be the same picture.

 * apart, nothing here is fetched until somebody actually opens a card, and
 * the export can inline them straight from this file. */
